Player Collider isn't found by Physics2D
I am trying to have a bullet fly out my ship. However, the bullet doesn't move and I think I have the error down to the fact, that it collides with my ship.
This is the Firing-Coroutine:
IEnumerator FireGun()
{
GameObject bulletClone = Instantiate(bullet, transform.position, player.GetComponent<Transform>().rotation);
bulletClone.GetComponent<BulletBehavior>().damage = damage;
bulletClone.GetComponent<Rigidbody2D>().AddForce(bulletClone.transform.up * bulletSpeed);
Physics2D.IgnoreLayerCollision(8, 9);
Debug.Log(bulletClone.transform.up * bulletSpeed);
Debug.Log(bulletClone.GetComponent<Rigidbody2D>().velocity);
Debug.Log(Physics2D.GetIgnoreLayerCollision(8, 9));
yield return null;
}
The Player does have the Layer 8, the Bullets do have the Layer 9 and the Log shows those layers get ignored. Log also shows, that a force of 0,500,0 should be applied, but the velocity is 0,0,0.
This is the error: ""MissingComponentException: There is no 'Collider' attached to the "Player" game object, but a script is trying to access it. You probably need to add a Collider to the game object "Player". Or your script needs to check if the component is attached before using it.""
This is my player: 
It clearly has a collider.
Does anybody know what is happening here? Thanks very much in advance Jan
Wait, am I blind or you didn't include the code where you try to access the collider?
I do not actually access the player collider directly. I try to Ignore the Collision via the layers. I used to have the following code:
Physics2D.IgnoreCollision(player.GetComponent<Collider2D>(), bulletClone.GetComponent<Collider2D>());
Which doesn't work either. "player" is a GameObject with pointing at the player.
However: Wierdly enough the Error $$anonymous$$essage is gone after I switched out the Collision detection again (Layers to colliders).... The bullets still don't move though.
Okay the problem is gone.
The collider error did just disappear... no clue why. The bullets now fly after I just cranked up the speed. Thanks everyone
Attach a collider to the player game object
The screenshot is the player game object. There is a collider.
Refering to my comment though: The error message is now miraculously gone after I went back to checking the collision via player and bullet collider directly.
Can't see anything wrong with your script as long as bullet speed is higher than 0 and the bullet's rigidbody is setup correctly. Good luck
